Abstract

A power optimization system and method for virtualized environments at least comprising a domain layer on which a plurality of virtual machines are implemented, a hardware layer and hypervisor layer configured for abstracting between the virtual machines of the domain layer and the hardware layer, wherein the system comprises a hardware interface to set a limit on the power consumption of at least one processing means implemented in a hardware layer and a software structure for performing an optimization of the available resource allocations for the running workload in terms of power consumption, wherein the software structure is an Observe-Decide-Act control loop structure, comprising an observe stage, a decide stage and an act stage, and wherein the observe stage interfaces with means configured for reading performance values inside at least one model specific register of the at least one processing means.

Description

TECHNICAL FIELD[0001]The present invention relates to a method for power optimization in virtual environments and system implementing the same.[0002]In particular, the present invention concerns a method for power optimization in datacentres having power budget constraints on the whole infrastructure, single clusters, and even single machines, and a virtualized environment implementing the method.BACKGROUND[0003]In the era of Cloud Computing, services and computational power are provided in an “as-a-Service” (aaS) fashion, reducing the need of buying, building and maintaining proprietary systems. In the last few years, many services moved from being proprietary to the as-a-Service paradigm: this, together with virtualization techniques, allows multiple applications to easily run on the same machine. However, the burden of costs optimization is left to the Cloud Provider, that still faces the problem of consolidating multiple workloads on the same infrastructure. As power consumption...
